' Application filed August 22, 1907. Serial No. 389,694.

To all whom it may concern: I

Be it known'that I, Iviia PETER BAGGER KNUDsEN, a subject of the King of Denmark, residing at No.66 Svammollevej, in,

mark, have invented certain new and useful Improvements in the Means for Lubricating Shafts, of which It is usually very difficult to efficiently high speed in consequence of the oil being trifugal acti0n.- This objection is obviated by the present inventionwhich enables the centrifugal acing the lubricant 'to the revolving parts cation. 7

The invention isillustrated in the accompanying' drawing, which shows a vertical section of the lubricating device for" the ball bearing o a rapidly rotating vertical shafts a is the shaft which rotates in contact with d is an inverted cup screwed to the shaft beneath the ball bearing, the lip of the cup dipping into the oil contained by a stationary vessel e constituted by an annular channel surrounding the shaft and having an outer the ball bearing 12. When the shaft a and with it the inverted cup d is caused to revolve rapidly, the oil in the vessel e is also caused to revolve with the. result that the wall of the oil latter to pass upwards over the innerlsurfaces of the outer wall of, the vessel 2 so as to constantly lubricate the balls 0. y

Having now described and ascertained the nature of my said invention and in what manner the same is to be performed Ideclare that what I claim is:' v

, 1. In a machine having a rapid rotating vertical shaft, a bearing r said-s aft and a stationary annular oil vessel arranged below the bearing and having its outer wall prolonged to in'close said bearing, a member fixed to said shaft below the bearing and dipping into the oil contained in the vessel in suclrmanner that when the shaft rotates the oil will be set in rotation and by the centrifugal action be forced up along the inner surface of the outer wall of the oil vessel and effect aconstant lubrication of the bearing.

2. In a machine having a rapidly rotating vertical shaft, a bearing for said shaft, and a stationary annular oil vessel arranged belo'w theibearing and havin its outer wall prolonged to inclose said earin an inverted cup fixed to the shaft beneat the bearing and having its lip dippingcinto the oil conwhen the shaft rotates thg oil will'be set in rotation and by the-cen rifugal action be forced up alon the inner surface of the outer vessel and effect :a constant lubrication of the bearing..- i v In witness whereof I have hereunto set my hand in presence of two witnesses.
